Solute clustering is known to play a significant role in the embrittlement of reactor pressure vessel (RPV) steels. In this study, previously unobserved manganese-, nickel-, and silicon-rich precipitates in the cementite phase of a thermally aged, lo

A simple Monte Carlo model has been used to simulate diffusional phase transformations occurring in binary alloys during thermal ageing. The results of the simulation are compared directly with atomic-scale chemical information obtained from position

This paper gives some suggestions and caveats on how to estimate the confidence limits on data obtained from atom-probe experiments. There are four sections covering autocorrelation, the use of contingency tables, estimation of ordering parameters an

Maintaining the safe operation of nuclear power plants (NPPs) is crucial. This requires fully understanding long-term irradiation mechanisms and their effects on components such as the reactor pressure vessel (RPV). The research community is collecti

Copper precipitation in irradiated RPV steels is well known to have a deleterious effect on mechanical properties. In order to understand the contribution of thermal ageing to RPV embrittlement a high copper (0.44 at.%), high nickel (1.6 at.%) model

In this paper three models are used to describe spinodal decomposition in Fe - Cr alloys. The challenge presented by this particular alloy system is that the wavelength of the decomposition is at the nanometre scale. The scale of the microstructure i

Algorithms have been developed for on-line analysis of data from the optical PoSAP, so that accurate flight time and position data can be derived for multiple ion events. The algorithm proceeds by first deriving accurate positions from the image obta

The Measurement of Composition During the Early Stages of the Spinodal Decomposition of Fe-Cr Alloys
Publikováno v:
MRS Proceedings. 186
The properties of many advanced alloys are derived from extremely fine-scale microstructures. This poses interesting questions about the measurement of composition on this scale. The phase separation of model Fe-Cr alloys has been been studied with t
